The Role of Respiratory Heat Exchange in the Production of Exercise-Induced Asthma, (2002)
Deal,E. Chandler , Jr., McFadden,E. R. , Jr., Ingram Jr.,R. H., Strauss,Richard H., Jaeger,James J.
By having our subjects inhale dry air at various temperatures ranging from subzero to 80 C in a random fashion, we have tested the hypothesis that it is the total heat flux in the tracheobronchial...
Slutsky, A S, Kamm, R D, Rossing, T H, Loring, S H, Lehr, J, Shapiro, A H, ...
Recent studies have shown that effective pulmonary ventilation is possible with tidal volumes (VT) less than the anatomic dead-space if the oscillatory frequency (f) is sufficiently large. We...
Evaluation of Role Played by Mediators of Immediate Hypersensitivity in Exercise-induced Asthma
Deal, E. Chandler, Wasserman, Stephen I., Soter, Nicholas A., Ingram, R. H., McFadden, E. R.
To determine whether mediators of immediate hypersensitivity played a role in the pathogenesis of exercise-induced asthma, we measured the concentration of histamine and neutrophil-chemotactic...
A critical assessment of the mechanism by which hyperoxia attenuates exercise-induced asthma.
Resnick, A D, Deal, E C, Ingram, R H, McFadden, E R
Recent data demonstrate that the magnitude of the heat loss that occurs from the respiratory tract during exercise correlates with the degree of post-exertional obstruction that develops in...
Ingram, R H, Wellman, J J, McFadden, E R, Mead, J
Bronchodilatation was produced in normal subjects by the inhalation of atropine, a parasympatholytic agent, and isoproterenol, a beta adrenergic stimulator. Density dependence of maximal expiratory...
Strauss, R H, Ingram, R H, McFadden, E R
To evaluate the roles of circulating hydrogen ion and lactate in the production of exercise-induced asthma, two experiments were performed. In the first, we exercised six asthmatic subjects to...
Influence of heat and humidity on the airway obstruction induced by exercise in asthma.
Strauss, R H, McFadden, E R, Ingram, R H, Deal, E C, Jaeger, J J
We examined the degree of airway obstruction that developed in eight asthmatics who exercised while breathing air under four conditions: (a) ambient room temperature and water content; (b) body...
Circulatory heat sources for canine respiratory heat exchange.
Solway, J, Leff, A R, Dreshaj, I, Munoz, N M, Ingenito, E P, Michaels, D, ...
We assessed the roles of the pulmonary and bronchial circulations as potential heat sources to the pulmonary airways during respiratory heat loss, by observing the changes in airstream temperature...
Impact of cuts in acute beds on services for patients.
Beech, R, Challah, S, Ingram, R H
The current redistribution of resources in the National Health Service will require a reduction in the number of acute beds in many district health authorities. The effect of such a reduction on...

Deep breaths and airway obstruction in asthma.
Spontaneously obstructed asthmatics constrict their airways after a DI. Such behavior is also seen in chronic bronchitis in which there is a prominent inflammatory component. Induced obstruction is...
Controlled-analysis of the effects of inhaled lignocaine in exercise-induced asthma.
Griffin, M P, McFadden, E R, Ingram, R H, Pardee, S
To determine whether anaesthesia of the intrathoracic airways would attenuate the development of exercise-induced asthma, we studied eight symptomless asthmatic patients by cycle ergometry after...
